Mortgage Rates Expected to Rise, Then Fall to 6.5% Next Year

The 30-year fixed-rate mortgage has experienced a consistent increase over the past six weeks, reaching 6.69% last week, up from 6.43% on July 2. This marks the highest rate observed since July 2025, according to data from Freddie Mac. Capital markets firm Optimal Blue projects that this upward trend will continue in the short term, anticipating the rate to reach 6.76% within the next three months. However, the firm forecasts a subsequent moderation, with rates expected to settle around 6.58% in 12 months. This forecast suggests that while mortgage rates may remain elevated for the medium term, a gradual decrease is anticipated for the following year. The current mortgage rate environment is significantly impacting the housing market, leading to slower home sales and a holding pattern for potential buyers. Optimal Blue's analysis indicates that rate sensitivity continues to suppress borrower demand. In July, purchase volume saw a notable decline of 12% as mortgage rates increased by 26 basis points. Furthermore, the purchase pull-through rate, which measures the proportion of mortgage applications that successfully close, decreased by 2.4 percentage points to 78.9%. Mike Vough, senior vice president of corporate strategy at Optimal Blue, commented on the market's sensitivity, stating that a 26-basis-point rise in rates was sufficient to cause a substantial drop in both purchase and refinance volumes compared to June's performance. He further noted that while the market is still performing better than the previous year, its momentum is fragile and highly dependent on future rate movements. The primary-secondary spread, a key indicator of lender costs and margins, is also subject to fluctuations. This spread, representing the difference between the mortgage rate offered to borrowers and the rate on a mortgage-backed security, currently stands at 1.01%. Optimal Blue predicts this spread may narrow to 0.94% in the upcoming month but could widen again to 1.06% over the next 12 months. Despite the current slowdown, there are underlying indicators of demand that offer some hope for the market's future. Optimal Blue's July data on mortgage activity reveals a slight deceleration in origination levels compared to preceding months. The firm's outlook suggests that while rising rates are a current headwind, the eventual return of rates closer to the 6.5% mark next year could stimulate a rebound in home sales in certain urban areas, potentially leading to a boom in transactions once the market stabilizes.
